new to parker's

[johnmac]

Hello to all....

I'm more of a mil-surp collector but was given this Parker double barrel with hammers. the barrel is a very ornate damascus pattern (but heavily coated in rust) and the reciever, screws, and all other metal parts are heavily engraved. I'm trying to find out some info on it as the markings are different than the ones posted on the identification pages of this site.
It's in pretty rough shape and i'm trying form an opinion as whether or not it is worth restoring or should i just get rid of it? I'm not even sure if it's the real deal.

Thanks,
John
